Due to the diversity of architectural shapes, as well as the influence of different regions and different climates, the roof drainage design has also become complex. The application of siphon drainage system in the drainage design of building roof has effectively solved this problem.
First, the composition of the siphon drainage system.
The siphon drainage system is mainly composed of rainwater buckets, pipes, elbows, tees, crosses, reducers, energy dissipation devices, inspection wells, etc.
Second, the characteristics of the siphon drainage system.
1.Drainage safety.
The siphon drainage system can quickly drain the roof rainwater and ensure that the building is not soaked by rainwater. At the same time, due to its high drainage efficiency, it can effectively avoid problems such as leakage and damage to the interior of the building caused by poor drainage.
2.Drainage economy.
Compared with the traditional gravity drainage system, the siphon drainage system has a higher drainage efficiency, which is able to reduce the number of pipes and the length of pipes, thus saving the space and cost of the building.
3.Eco-friendliness.
The siphon drainage system adopts a closed pipe system, which can effectively reduce the impact on the surrounding environment. At the same time, because it adopts the method of rainwater collection and utilization, it can realize the reuse of rainwater and has high environmental protection.
3. Key points of the design of the siphon drainage system.
1.Determine the design flow rate.
According to the area, shape, use function and other factors of the building, the design flow rate is determined, so as to determine the pipe diameter, length and other parameters of the siphon drainage system.
2.Choose the right rain bucket.
According to the actual situation of the building, choose the appropriate rainwater bucket model and quantity to ensure the smooth drainage system.
3.Optimize piping arrangements.
On the premise of ensuring drainage efficiency, the number and length of pipes should be minimized, and the pipe layout should be optimized to reduce the space and cost of the building.
4.Set up an energy dissipation device.
An energy dissipation device is set at the end of the drainage system to reduce the impact of water flow on pipes and buildings, and ensure the stability and safety of the drainage system.
5.Inspection and maintenance.
Regularly inspect and maintain the drainage system to ensure its normal operation and service life.
IV. Conclusions. With the continuous improvement of people's requirements for building drainage system, the application of siphon drainage system in building roof drainage design is becoming more and more extensive. It has the characteristics of drainage safety, economy and environmental protection, and can effectively solve the drainage problem of buildings. In the future development, with the continuous progress and innovation of technology, the siphon drainage system will be more complete and mature.
